ras_formats man page

NCAR Graphics and NCAR View applications are built upon a common library that provides read and write access to raster imagery. The table below summarizes the support that is provided for all the different formats. Note that a format may be writeable but not readable, and that a compressed image may be readable but not writeable. By default, a raster image is written as compressed if possible. For those applications that key upon the filename to determine the raster format, or allow a -ifmt or -ofmt, the extension, as listed below, should be used without the "." in front (e.g. use "hdf", not ".hdf").
